1 Claim.

This invention relates to receptacles from sheet stock.

This invention has utlity in sealed substantial paper or fiber-walled cans' adaptable to be coated withexposure to slight maximum flexure and resistant to internal and external load. These containers are suitable for receiving hot pourings of readily congealable materal, suchas bituminous matter. Asphalt as so handled may enter the vessel with the vessel retaining its form independent of external holding means or mold. Furthermore, there is opportunity for positioning the closure in sealing position independently, ofthe oneperforming such operation, being exposed to direct contact with the hot liquid.

Referring to the drawing:

Fig. 1 is a view of the scored cut blank for the body or main portion of the vessel or receptacle;

Fig. 2 is a view ofthe bottom head or disk for the closure base;

Fig. 3 is a side elevation of the body of Fig- 1 stitched into tubular form and collapsed, .0r in the at, for storage or ready supply to the place to be charged;

' Fig. 4 is aside elevation, with parts broken away, of the charged container;

Fig. 5 is a plan view of the sealed top of the charged container of Fig. 4, involving the major tongues in edge overlapping relation;

Fig. 6 is a bottom plan view of the base of Fig. 4 in which the tongues marginally about as folded inward and are stitched to each other and the disk of Fig. 2; and

Fig. '7 is a view similar to Fig. 5, wherein the polygonal group of tongues is in Octagon arrangement instead of hexagon as in Fig. 5.

Sheet stock as of paper board, liber board, or box board, with the grain or general liber direction approximately parallel to a line I, gives rigidity to this main body for portions 2, 3, 4.-

The portion 3 is separated from the portion I by a score 5 and from the portion 4 by a score 6, parallel to each other. -These scores-5, 6, intercept parallel scores 1, 8. The score 1 has therebeyond annular series of minor tongues 9 with V-cut outs I therebetween having short spacing II from the score line 1. -The scores 5, 6, are medially of these trapezoidal tongues 9.

Remote from this series of minor tongues 9 is a series of major tongues I2 extending from the score line 8. These rectangular tongues I2, as the major tongues, have the major score lines 5, 6, extend therethrough. From the line I of the blank, major sectional tongue I3 has coop- (Cl. '22g-4.5)

eration with minor tongue I 4 as seam I5 effects closing of this main body into a tubular set-up.

This seam I herein comprises sets of stitchingv IB in closer or more effective holding proximity to each other adjacent the score line 1 and gradually opening out into wider stitchportions I1 toward the score line 8. This is a matter of economy in manufacture, in that the greater load strain near the base score line 1 has re- 10 sponse in' the closer stitching holding portion I6, whilev as the top portion is reached themore Vopen stitching I1 is sufficient for. positive holding and efficient sealing.

At assembly, this collapsed body folded on the l5 score lines 5, 6, is opened out to have in such tube, a disk I8, which may more or less approach or depart from circular form. This disk I8 on its inside may have coating I9 as say the inside of the tubular body may be similarly coated. In the event there is use of the' vessel with a substance tending to adhere to the stock, and which adherence it is wished to defeat, there is importance in selecting this coating. This importance liesnot only for ready severance and thereby saving the full volume of the contents, but may be against soaking intov or attacking of this body by the charge. In the instance of a product in which more difficulty has been ext perienced, hot asphalt, a coating has been adopt- 3" d which will resist attack on the ber or paper board by the hot asphalt. This coating will permit ready tearing lof the paper clear of the asphalt as the asphalt is congealed. Forms of this coating substance are disclosed in applications 3o for United States Letters Patent by Jackson H. Rollins and VWalter E. Hatch: Ser. No 232,015, filed Sept. 27, 1938, Coating; and Ser. No. 276,440, .filed May 29,-1939, Special coating composition values. f

With this disk I8 in position and its coating side I9 on the inward or upper side, the opposite or' outer side of the disk I8 may have folded thereagainst the minor tongues 9. These minor tongues 9 areof such dimension that in the in- 4b ward fold there is effective closure of the V-cut' cuts I0, and as so closed stitching 20 not only assembles a pair ofvtongues with each other but anchors such tongues with the disk I8 in bringing the sides of the adjacent tongues 9 into abutting relation. There is thus established a curved or circular contour for the head at the base of this container. Y

The opposite end has the tongues I-2, I3, I4, up-

wardly projecting as the container has open top 55. and is in position to be charged. As there is flowed into this container the material, whether granular, liquid or molten, at the full charge the tongues may be in opposite pairs laid toward each other. Preferably the tongues having the scorings 5, 6, thereacross are the flrst pair of opposite tongues to be laid down. The next pair of tongues' may include the tongue portions I3, I4, having the seam thereacross. In the hexagonal set-up this will leave a third` pair of tongues to be the last or outer pair as completing the sealing overlapping, and as their en ds may to some extent overlap, stitching 2| is a holding .of this outer flap pair in at position across this second head or top. In this anchoring by the stitching 2|, the tool for these wire staples may be thrust into position on opposite sides'of the flaps as stapled and thus insure an eicient anchoring. These flaps as having the coating I9 on the inner side'provide this non-adherent face as exposed to the poured asphalt 22 as close thereagainst.

Notwithstanding the weight of a substance as poured asphalt, the strength of the seam I5 as held by stitching I6 is sufficient for charging of the container as standing alone. As the pour of asphalt approaches the top, there is of course less load and the widened stitching I1 is sufficient for holding in the top region. The fact that the scorings 5, 6, are away from the tongues atthis overlapping tongue head or top is'an additional factor that there is not a weakening for the contents to soak in or penetrate the fiber or box board paper. The scores 5, 6, in opening to approach a cylinder in the instance of the coating I9 adopted herein, do not tend in such flexure to fracture. There is absence l of scoring toward polygonal head portion adjacent the base of the several tongues I2. However, the base portions of these several tongues approach straight lines and thereby cause this can-shaped cylindrical charged body to flex to r'ward the corners of the polygon with absence of definite defining thereof to the extent which would introduce a weakened corner. There is thus no weakened corner for outside severe abrasion. There is not sufficient flexure to detract from continuity of the .coating I9 on the inside. The resulting container is one which may be readily rolled as on its side in the approachingcylindrical form, but in this rolling there is condition of stability to retain a. position against rolling unless caused to shift therefrom. This stable condition is due to the configuration as departing from cylindrical form at the polygonapproaching head end or top.

The fact that the fiber of the stock runs lengthwise gives flexibility for approaching cylindrical form and stiffness against crushing between the heads. Accordingly, with these containers i'n the region of 22 to 36 inches high and 13 to 15 inches in diameter, they may be charged with asphalt up to the neighborhood of 5G to 100 pounds and stacked on end for as many as three or four courses high. This is a position of stability for storage or transportation.

As the purpose is one for opening one of these containers, the flaps I2 may be readily torn and opened out for pouring the contents in the event it be granular, while if it be congealed into a body, as asphalt, there may be a stripping of the container therefrom or other removal, depending on whether or not the receptacle be for single service.

In the instance of Fig. 7, there is shown octagonal flaps or tongues 23 instead of the hexagonal 'flaps or tongues I2 in the approach to regular polygonal form for one end of the vessel, herein dened as the top.

What is claimed and it is desired to secure by United States Letters Patent is:

A two 'part container, polygonal at one end and circular at the other, -one of said two parts of the container being a disk closure for the circular end of the container, the other of said .two parts being a tubular body having at one end an annular series of rninor tongues overlapping the disk with the body cylindrical contour thereabout, and major tongues at the other end of the body for the free ends of said latter tongues to overlap and the bases of said latter tongues to define sides of a polygon with the corners of the polygon lying substantially in the cylindrical surface of the cylindrical extension dened by said disk, said cylindrica1 contour suf.- ciently persisting for rollability of the charged container, and the polygon being sulliciently pronounced for stability against free rolling of the HARRY W.
